SERVICE UPDATE
SUBJECT:

Service Update for Inventory and Customer Vehicles
Front Seat Mounted Speaker Buzz
Expires with Base Warranty

MODELS:

2013 Cadillac XTS
Equipped with Front Seat Mounted Speakers (UQS)

This service update includes vehicles in dealer inventory and customer vehicles that
return to the dealership for any reason. This bulletin will expire at the end of the involved
vehicle's New Vehicle Limited Warranty period.
PURPOSE
This bulletin provides a service procedure to replace the fasteners and the bezel for the front
seat mounted speakers on certain 2013 model year Cadillac XTS that are equipped with front
seat mounted speakers (UQS). The fasteners may lose clamp load and cause a buzz noise,
especially when listening to stations with talk radio.
This service procedure should be completed as soon as possible on involved vehicles
currently in dealer inventory and customer vehicles that return to the dealer for any type
of service during the New Vehicle Limited Warranty coverage period.
VEHICLES INVOLVED
All involved vehicles are identified by VIN in the Global Warranty Management System –
Investigate Vehicle History Application. Dealership technicians should always check this site to
confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is
important to routinely use this tool to verify eligibility because not all similar vehicles may be
involved regardless of description or option content.
Additionally, a list of involved vehicles currently in dealer inventory is available on the “Service
Update Bulletin Information” link under the “Service” tab in GM GlobalConnect (US) or attached
to the GlobalConnect message (Canada) used to release this bulletin. Customer vehicles that
return for service, for any reason, and are still covered under the vehicle's base warranty should
also be checked for vehicle eligibility.

DEALER PROGRAM RESPONSIBILITY
Whenever a vehicle subject to this service update enters your vehicle inventory, or is in your
facility for service in the future, and the vehicle is still covered under the New Vehicle Limited
Warranty, you must take the steps necessary to be sure the service update correction has been
made before selling or releasing the vehicle.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that
may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the tools,
equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to
your vehicle, or that your vehicle will have that condition. See your dealer for information on whether your vehicle may benefit from the information.
